CARD CLOTHING.
Application filed July 21, 1926. Serial No. 124,076.
poses.
It is the general object of my invention to provide means for ca using the card clothing to lie more smoothly against the roll or cylinder and to be more firmly retained in position thereon.
A further object strength and durability To the attainment of vide' a facing layer of other suitable material, face of the body portion or backing of the card clothing. The us layer possesses is to increase the of the card clothing. these objects, I prothin sheet steel or covering the outer e of such a facing important advantages which will be hereinafter described and more fully pointed out in the appended claims.
shown in the drawings A preferred form of the invention is in which Fig. 1 is a side elevation of a portion of card clothing embodying my invention;
Fig. 2 is a plan view of the reinforcing strip of metal facing;
Fig. 3 is a side elevation of a modification;
and
Figs. 4 and 5 are enlarged detail sectional views of the structure shown in Figs. 1 and 3 respectively.
Referring to the drawings,
my improved card clothing comprises a body portion or backing 1O whichmay suitable woven material A facing be of leather or of a such as is commonly used in the manufacture of card clothing.
member or covermg strip 12 is placed against the outer face of the body member 10 and the U-shaped pins 14 are inserted through aligned body 10 and in the faci 'lhe facing strip 12 difi'erent kinds of thin as copper, zinc or tin,
perforations in the ng strip 12.
may be formed of sheet material such but I have found that very satisfactory results are attained by the use of a sheet erably not over four or an inch in thickness.
of very thin sheet steel,
preffive thousandths of Steel of this thickness may be readily perforated by the needles which perforate thebackin or body ortion prior to the insertion o the pin wires, and at the same time it possesses strength and resilience to an extent sufficient for the purpose intended.
In the manufacture o f my improved card 'ing a facing clothing, the facing strip 12 is fed through the machine with the backing 10, and both layers are simultaneously perforated and the wires are inserted therein practically as a single operation.
The needles which make the perforations are somewhat larger than the pin wire, so that the pins fit rather loosely in the openings through the metal facing. This is of importance, as it permits a certain yielding movement of the pins and does away with the tendency of the pins to break off at the point where they pass through the metal plate.
his thin sheet steel facing also possesses considerable resilience and causes the card clothing to hu tightly against the drum or cylinder on w ich it is wound, preventing buckling of the card clothing and causing it to retain the accurate cylindrical form required for carding operations.
The metal facing also increases the tensile strength of the card clothing and permits it to be wound on the cylinder under greater tension, thus securing a tighter fit of the clothing against the cylinder.
In Fig. 3 I have shown a modified construction in which the layer of sheet material is applied at the back rather than on the face of the body portion. While this construction lacks certain of the advantages of the preferred form, it substantially increases the strength of the card clothing and permits the same to be wound on the cylinder under a greater tension than has been heretofore used.
Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims, but what I claim is:
1. Card clothing comprising a relatively soft in-retaining body portion, a thin flexible ayer of resilient sheet material formfor said body portion, and a pluralit of pins extending tightly through said bo y portion and loosely through perforations in said facing layer.
2. Card clothingj comprising a relatively soft pin-retaining ody portion, a thin flexible stiffening layer of resilient sheet material forming a facing for said body portion, and a plurality of pins extendina through aligned perforations in said body portion and said facing layer, said facing layer havaligned perforations in said body portion ing perforations therein for said pins which and said steel facing layer and loosely are of slightly larger diameter than the pins. fitting the perforations in said facing layer. 10
3. Card clothing comprising a body por- In testimony whereof I have hereunto af- 5 tion, a thin layer of sheet steel forming a fixed my signature.
facing for said body portion, and a plu rality of Ushaped pins extending through LESTER R. ARNOLD.
